WHEN you hand out cake to a group of overexcited teenagers, things are only going to head in One Direction. Utter chaos.

The boys were presented with a cake to celebrate Niall Horan’s 18th birthday as they performed at London’s G-A-Y club. That quickly went in his face.

The boys – who went straight to No1 when their debut single, What Makes You Beautiful sold a whopping 153,965 copies – were then given another. That got chucked in the crowd, on the floor and at each other. Surprisingly, only Harry Styles stacked it.

“I tried to style it out,” he wrote on Twitter. “It just didn’t work.”

In other dangerous activities, 1,000 people turned up in Maida Vale to see the boys arrive at Radio 1 HQ for the chart show yesterday. So Beeb bods cancelled and had them interviewed at a “secret location” instead. Boooo!
